Electrochemical sensors for point of use diagnostics from Canatu

Electrochemical biosensors

Electrochemical biosensors using Canatu carbon nanotubes offer industry-leading sensitivity and bring lab-level clinical analysis anywhere.


Electrochemical biosensors for point-of-care analysis

Electrochemical biosensor functions by converting biochemical events into electrical signals. At its core is the electrode, providing stable support for immobilizing biomolecules and facilitating electron movement. Carbon nanotubes stand out as ideal electrodes, thanks to their large surface area and electrical conductivity, resulting in high performance in terms of analytical sensitivity.

Canatu creates the most advanced carbon nanotubes through a unique dry deposition method. The inherently large specific surface area, high electrical conductivity, and tailorable surface chemistry make Canatu CNT an ideal electrode for electrochemical biosensors. Utilizing Canatu CNT, electrochemical biosensors achieve industry-leading sensitivity and high reproducibility.

  • Sensitivity: Strong signal and low detection limit attributed to high electrical conductivity, a pristine CNT surface, and large contact area with the analyte
  • Versatility: Ability to measure various substances across a broad range of fluidic samples, including sweat, saliva, blood, and urine
  • Scalability: Proven mass production process with the capacity for manufacturing millions of sensors annually

Electrochemical biosensors bring the lab to anyone’s hand

Electrochemical biosensors bring the lab-level analysis virtually anywhere. Point-of-care electrochemical detection is on the rise, enabling rapid on-site detection of various biomarkers. These electrochemical biosensors hold great promise in transforming medical diagnostics, offering accurate and timely results, while making low-cost, easy-to-use, and accessible diagnostics possible.

Electrochemical biosensor research

Our advancements in electrochemical biosensor solutions are progressing rapidly. A concrete proof of our capabilities in electrochemical detection is evidenced by a growing list of academic publications. Explore a summary of our recent research with the ecosystem partners and academia.


Electrochemical biosensors for detecting painkiller concentrations

For over four years, Canatu has collaborated with leading Finnish universities and Helsinki University Hospital to develop electrode strips for point-of-care measurements of painkiller concentrations. In this partnership, test strips capable of quantitatively detecting painkillers, including paracetamol and opioids, have been created. Given the widespread misuse of these medications, they are common causes of poisoning.

The developed test strips utilize the highly sensitive and repeatable Canatu CNT electrode platform, ensuring a high signal-to-noise ratio. These test strips have been validated in three early clinical studies, including the clinical validation of a test strip designed to measure paracetamol (acetaminophen) concentrations from small finger-prick blood samples.
